Beginner's Guide: ISO27001 Compliance
Approximately 44,000 organizations have achieved ISO 27001 certification, and the trend is upward each year. This growth indicates a rising recognition of its significance in today’s business landscape. However, comprehending this standard can be challenging for those new to the concept.
This article will offer an overview of ISO 27001, its importance, and best practices for attaining certification, among other insights.
What is ISO 27001?
ISO/IEC 27001 sets the international standard for information security, detailing the criteria for a comprehensive Information Security Management System (ISMS). It employs a risk management approach, encompassing personnel, procedures, and technology. It’s based on a set of ISO 27001 controls and measures, which organizations can use to achieve information security. Attaining ISO 27001 certification signifies that an organization’s information security practices are consistent with global best practices.
The ISO 27001 standard mandates the establishment of procedures to address various components of the ISMS, which include:
- Information security risk management (Identifying the risks and determining the methods for their treatment.)
- Monitoring, measurement, analysis, and evaluation (Assessing the effectiveness of the information security management system.)
- Improvement (Evaluating and addressing nonconformities.)
Who Needs ISO 27001?
Businesses expanding into international markets can show their commitment to safeguarding customer data by adopting ISO 27001. This standard helps organizations to assure customers that they are managing the confidentiality, integrity, and availability of information through a systematic risk management process. Its main goal is to enable organizations to develop, implement, sustain, and consistently enhance their Information Security Management System (ISMS).
Why is ISO 27001 Important?
The ISO 27001 standard serves as a robust framework for maintaining the security of your company’s information, provided it is implemented correctly. It offers a systematic method for the implementation, integration, and continual enhancement of your Information Security Management System (ISMS).
By adopting this standard, you can safeguard assets against internal and external threats through:
– A thorough understanding of the organization’s needs, requirements, and risk appetite.
– The application of policies, procedures, and controls to govern these risks within the organization’s established tolerance levels.
– Regular monitoring of performance in adherence to these standards.
What are the ISO 27001 requirements?
While ISO 27001 centers on the implementation of an ISMS (Information Security Management System), it does not enforce a universal set of controls for compliance. This is due to the recognition that each organization is distinct, with specific information security needs. Rather than prescribing a uniform set of requirements, ISO 27001 obliges organizations to engage in activities that guide their selection of appropriate controls. This blog post will outline those activities and provide guidance on how to execute them.
Mandatory ISO 27001 requirements
The most important activities when implementing ISO 27001 are:
- Scoping your ISMS
Documenting the scope of an ISMS involves defining the information assets that require protection. There are likely more information and locations where information is stored than initially anticipated, so it is crucial to thoroughly identify all relevant aspects of your organization. The process for this is detailed in Clause 4.3 of the Standard.
- Conducting risk assessment
Clause 6.1.2 of the Standard mandates that organizations must “define and apply” a risk assessment process. This process is a structured, top management-led activity that forms the cornerstone of the Information Security Management System (ISMS).
- Defining a risk treatment methodology
A Risk Treatment Plan (RTP) is a crucial component of an organization’s ISO 27001 implementation process, as it outlines the organization’s approach to managing identified threats. Organizations can decide on the most effective way to address a risk by consulting the controls specified in Annex A of ISO 27001.
Organisations are also required to complete the following mandatory clauses:
- Information security policy and objectives (clauses 5.2 and 6.2)
- Information risk treatment process (clause 6.1.3)
- Risk treatment plan (clauses 6.1.3 e and 6.2)
- Risk assessment report (clause 8.2)
- Records of training, skills, experience and qualifications (clause 7.2)
- Monitoring and measurement results (clause 9.1)
- Internal audit programme (clause 9.2)
- Results of internal audits (clause 9.2)
- Results of the management review (clause 9.3)
- Results of corrective actions (clause 10.1)
Annex A: Reference control objectives and Controls
Annex A offers organizations a catalog of controls for assessing their relevance in risk mitigation. While these controls are not compulsory, it is essential to evaluate whether all the necessary Annex A controls have been reviewed and that none that are required have been excluded.
Depending on the controls your organisation selects, you will also be required to document:
- Definition of security roles and responsibilities (clauses A.7.1.2 and A.13.2.4)
- Inventory of assets (clause A.8.1.1)
- Acceptable use of assets (clause A.8.1.3)
- Access control policy (clause A.9.1.1)
- Operating procedures for IT management (clause A.12.1.1)
- Secure system engineering principles (clause A.14.2.5)
- Supplier security policy (clause A.15.1.1)
- Incident management procedure (clause A.16.1.5)
- Business continuity procedures (clause A.17.1.2)
- Statutory, regulatory, and contractual requirements (clause A.18.1.1)
- Logs of user activities, exceptions, and security events (clauses A.12.4.1 and A.12.4.3).
- Statement of Applicability
The Statement of Applicability (SoA) is a crucial document in the information risk treatment process. It details the Annex A controls that have been implemented or excluded, providing reasons for these decisions. Additionally, it should contain further details about each control and references to the corresponding implementation documentation.
- Document Information Security Policies
The policies you establish will form the cornerstone of your information security strategy. They should be clearly defined, approved, disseminated, and communicated across the organization. Your policy must be pertinent to your organization, articulate your information security goals, demonstrate a commitment to meeting ISO 27001 standards and the associated Annex A controls, and promote the ongoing enhancement of the ISMS.
- Operationalize your ISMS
To operationalize your Information Security Management System (ISMS), implement processes that align with Clauses 6 through 10. These include planning, risk assessment, document control, procedure implementation, and monitoring, ensuring that your strategy and policies are continuously updated and improved. It’s crucial to synchronize your strategy and policies with tactical activities, demonstrating that your ISMS is both operational and repeatable. This involves the ability to assess risks, carry out control processes, monitor metrics, and identify and execute corrective actions.
Internal Audit
Completing an internal audit is essential for the independent evaluation of your ISMS. It assists in identifying any nonconformities, assessing the effectiveness of your ISMS, and uncovering areas for potential enhancement.
Implement Corrective actions from the internal audit
Following the findings of your internal audit, you should implement corrective actions for any identified nonconformities. Your action plan should detail:
- The specific nonconformity.
- Your strategy for correction, control, and management of the nonconformity’s consequences.
- The underlying cause of the nonconformity.
- The efficacy of your corrective measures
ISMS Review
Senior-level management must regularly review the ISMS to guarantee its effectiveness and alignment with the organization’s objectives.
Establish periodic review meetings to cover:
– Changes within or outside the organization that affect the ISMS.
– Progress reports on previous ISMS reviews.
– Feedback from internal audits, risk evaluations, and stakeholders.
– Any modifications or enhancements.
Ensure that the outcomes and follow-up actions of your reviews are well-documented.
Choose an Accredited Certification Body
When you’re prepared to pursue ISO 27001 certification, it’s necessary to select an accredited certification body to conduct the audits—both Stage 1 and Stage 2. The Stage 1 audit focuses on reviewing your documentation to assess your preparedness for Stage 2. The Stage 2 audit is a comprehensive examination of your ISMS to verify compliance with the standards, effective implementation of the necessary controls, and adherence to your internal policies and procedures.
Implement corrective actions from identified Nonconformities
Audit findings can present an opportunity to enhance your information security strategy. Should your auditor pinpoint any nonconformities, it’s crucial to execute corrective measures and monitor their efficacy.
What are the control changes in Annex A?
Several Annex A controls have been merged, while 11 have been added:
- Even though no controls have been removed, ISO 27001:2022 lists only 93 controls rather than ISO 27001:2013’s 114. This is due to the large number of merged controls (56 into 24).
- These controls are grouped into 4 ‘themes’ rather than 14 clauses. They are:
- People (8 controls)
- Organisational (37 controls)
- Technological (34 controls)
- Physical (14 controls)
- The completely new controls are:
- Threat intelligence
- Information security for use of Cloud services
- ICT readiness for business continuity
- Physical security monitoring
- Configuration management
- Information deletion
- Data masking
- Data leakage prevention
- Monitoring activities
- Web filtering
- Secure coding
- In ISO 27002, the controls also have five types of ‘attribute’ to make them easier to categorise:
- Control type (preventive, detective, corrective)
- Information security properties (confidentiality, integrity, availability)
- Cyber security concepts (identify, protect, detect, respond, recover)
- Operational capabilities (governance, asset management, etc.)
- Security domains (governance and ecosystem, protection, defence, resilience)
The changes of ISO/IEC 27001:2022
ISO 27001:2022 does not present significant deviations from its 2013 predecessor; however, it introduces some noteworthy modifications. These changes are primarily associated with Annex SL, which is the overarching structure shared by all new ISO management system standards, and not specifically with information security measures.
Context and scope
You must now identify the “relevant” requirements of interested parties and determine which requirements will be addressed through the ISMS.
The ISMS must now explicitly includes the “processes needed and their interactions”.
Planning
Information security objectives must now be monitored and “be available as documented information”.
There is a new subclause on planning changes to the ISMS. This does not specify any processes that must be included, so you should determine how you can demonstrate that changes to the ISMS have indeed been planned.
Support
The requirements to define who will communicate, and the processes for effecting communication, have been replaced by a requirement to define “how to communicate”.
Operation
The requirement to plan how to achieve information security objectives has been replaced by a requirement to establish criteria for processes to implement actions identified in Clause 6, and to control those processes in line with the criteria.
Organisations are now required to control “externally provided processes, products or services” relevant to the ISMS rather than just processes.
